I am about to start a new project. Using VS2010, Silverlight 4, and RIA Services are a given. However, due to the web server we have available, there is some question of whether we can use .NET 4 or whether we will have to stick to .NET 3.5. I know that RIA Services can work with .NET 3.5. But what I'm curious about is whether there is any difference in functionality with RIA services between 3.5 and 4. Would I be missing any big features? If so, I might push harder on the server team to get .NET 4 installed in time.

A:
Are you sure that you can use .NET 3.5 on the server with RIA Services ?
The DLLs I have in C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Server\ all have a target runtime of v4.0.30319.

Y'know, I've been trying to prove that to myself since I wrote this question. I know that the betas of RIA Services were available for VS 2008 / .NET 3.5. But I see the same thing you do. Still investigating...

Indeed the download page does not have anything but the VS 2010 install from what I can find. I guess that answers my question then. :-)

I agree, I had run the beta with .NET 3.5. And I could not find a page that states the .NET version dependency.

WCF RIA Services V1.0 only runs on .NET 4.0. The Beta for 3.5 is available and 'go live', but it is not officially supported. If you have a choice, I'd recommend upgrading to .NET 4.
